Scenario (not to scale) for the intersection between the molecular disc (the red and blue ellipse) and the ionisation bicone. In the disc of the galaxy, traced by the molecular gas, we mark the AGN position (white star) and the proposed interactions between the two gas phases (black asterisk symbols). The 300-pc radio (at 8.46 GHz) and soft X-ray (below 1 keV) emission is depicted in yellow. Along the ±5″ lines of sight, we draw clouds on the edge of the bicone, colour-coded depending on whether the gas is blueshifted or redshifted.
